The Haakaa Silicone Orthodontic Bottle Teat attachment is fully compatible with all Generation 3 bottles (glass and silicone) and storage containers, transforming them into a handy baby bottle! 

The Orthodontic Bottle Nipple is designed to provide the most natural feeding experience possible for you and your baby. The orthodontic thumb-shaped teat mimics the shape of a mother's nipple during breastfeeding, and the offset position allows you to safely feed your baby without completely inverting your bottle. The anti-colic vent allows your baby to feed continuously without taking in air bubbles or having to gasp for air between latches.
